STIFEL REPORTS THIRD QUARTER 2018 FINANCIAL RESULTS

ST. LOUIS, MO – Stifel Financial Corp. (NYSE: SF) today reported record net income available to common shareholders of $101.5 million, or $1.25 per diluted common share on net revenues of $738.3 million for the three months ended September 30, 2018, compared with net income available to common shareholders of $64.2 million, or $0.79 per diluted common share, on net revenues of $721.2 million for the third quarter of 2017.

For the three months ended September 30, 2018, the Company reported non-GAAP net income available to common shareholders of $110.1 million, or $1.35 per diluted common share. The Company’s reported GAAP net income for the three months ended September 30, 2018 was primarily impacted by merger-related expenses. Details discussed below and in the “Non-GAAP Financial Matters” section.

Chairman’s Comments

“I’m pleased with our results which highlight the strength of our diversified business model. Record Global Wealth Management revenue was driven by another record quarter for both net interest income and fee-based revenues. Additionally, our continued focus on recruiting resulted in the addition of 31 net new advisers, our highest quarterly increase in roughly 10 years, excluding acquisitions.  The increased operating leverage from the growth in our recurring revenue lines and our continued focus on cost discipline enabled us to overcome slower seasonal revenues and generate pre-tax margins of nearly 21%, double digit sequential EPS growth, as well as returns on common and tangible equity of 15.5% and 25.2% respectively. Year-to-date, our EPS is up nearly 50% as our pre-tax margins have improved by nearly 300 bps to 18.8%.  Looking forward, the momentum we are building in our recruiting efforts should help to drive revenue growth in our wealth management business and our investment banking pipelines remain strong. As such, assuming continued growth in the U.S. economy, I’m optimistic about our future,” stated Ronald J. Kruszewski, Chairman & CEO of Stifel.

For the nine months ended September 30, 2018, the Company reported net income available to common shareholders of $272.9 million, or $3.35 per diluted common share on net revenues of $2.2 billion, compared with net income available to common shareholders of $177.8 million, or $2.21 per diluted share, on net revenues of $2.1 billion for the nine months ended September 30, 2017.

Investment Banking Revenues

Investment banking revenues were $169.0 million, a 7.1% decrease compared with the third quarter of 2017 and a 4.9% increase compared with the second quarter of 2018.

Effective January 1, 2018, the Company adopted Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers, which provides accounting guidance on the recognition of revenues from contracts and requires gross presentation of certain costs that were previously offset against revenue. This change was applied prospectively from January 1, 2018 and there is no impact on our previously presented results. With our adoption of the new revenue recognition standard on January 1, 2018, capital raising and advisory fee revenues are no longer presented net of the related out-of-pocket deal expenses. As a result, capital raising and advisory fee revenues and other operating expenses are higher in the third quarter of 2018 by an identical $9.7 million, with no impact to net income.

Asset Management and Service Fee Revenues

Asset management and service fee revenues were a record $200.7 million, an 11.6% increase compared with the third quarter of 2017 and a 0.6% increase compared with the second quarter of 2018. The increase from the comparative period in 2017 is primarily attributable to the growth in fee-based accounts. See Asset Management and Service Fee Break-down table.

Net Interest Income

Record net interest income of $121.3 million, a 21.0% increase compared with the third quarter of 2017 and a 3.5% increase compared with the second quarter of 2018. The increase is primarily due to growth of interest-earning assets and interest-bearing liabilities, as well as higher interest rates.

Compensation and Benefits Expenses

For the quarter ended September 30, 2018, compensation and benefits expenses were $422.3 million, which included $5.5 million of merger-related and severance expenses (non-GAAP adjustments). This compares with $448.4 million in the third quarter of 2017 and $442.2 million in the second quarter of 2018. Excluding the non-GAAP adjustments, compensation and benefits as a percentage of net revenues were 56.5% in the third quarter of 2018 (non-GAAP measure).

Non-Compensation Operating Expenses

For the quarter ended September 30, 2018, non-compensation operating expenses were $175.5 million, which included $6.1 million of merger-related and litigation-related expenses (non-GAAP adjustments). This compares with $164.6 million in the third quarter of 2017 and $182.2 million in the second quarter of 2018. Excluding the non-GAAP adjustments, non-compensation operating expenses as a percentage of net revenues for the quarter ended September 30, 2018 were 22.9% (non-GAAP measure).

Provision for Income Taxes

The GAAP effective income tax rate for the quarter ended September 30, 2018 was 26.1%. This compares with an effective income tax rate of 38.5% for the third quarter of 2017 and 26.2% for the second quarter of 2018. The provision for income taxes for the three months ended September 30, 2018 was primarily impacted by the tax reform enacted in the fourth quarter of 2017 that, among other things, lowered the federal corporate income tax rate from 35% to 21%.
